A genetic characterization of a species can guide efforts to collect and conserve germplasm for future breeding programs. The <em>Croton</em> genus belongs to the Euphorbiaceae family, which has approximately 1,300 species, is widely distributed in tropical and subtropical regions of the world, and has a wide range of ethnobotanical and medicinal uses. The aim of this research was to study genetic variability by analyzing sequences of the internal transcribed space region (ITS1 5’-TCCGTAGGGAACCTGCGGC-3’ and ITS4 5’-TCCTCCGCTTATGC-3’) of ribosomal DNA (rDNA) of a Croton population from forested areas in the Department of Norte de Santander in the municipalities of Chinacota, Pamplona and El Zulia. The results indicated considerable genetic variability in the <em>Croton</em> population, with a nucleotide similarity ranging from 54 to 99% and phylogenetical grouping according to the place of origin. The information gained from the ITS region can be a useful parameter for diversity evaluations and phylogenetic studies since there are no similar studies on <em>Croton</em> in this department in northeastern Colombia.</p>}, number={1}, journal={Revista Colombiana de Ciencias Hortícolas}, author={Chaves-Bedoya, Giovanni}, year={2022}, month={Jan.}, pages={e13592} }
